If you look at the top of libs/libmyth/storagegroup.cpp, you'll see:

const QStringList StorageGroup::kSpecialGroups = QStringList()
    << "LiveTV"
//    << "Thumbnails"
    << "DB Backups"
    ;

The "Thumbnails" special storage group will be uncommented as soon as I 
can get around to finishing up the patch I've been working on that puts 
the preview pixmaps, a.k.a. Thumbnails, in their own storage group.
